**TLDR:** An approach in which data from a source system is replicated into another environment for analytical or operational use.

<p>Source system replication is used to make data available in other environments without placing direct load on production systems. It is common in reporting, data science, and integration scenarios. However, teams must carefully manage how fresh the replicated data is, whether it is copied fully or selectively, and how schema changes are handled. Replication is not just copying data, but designing controlled data access.</p>
